RICHARD B. IVIARSII, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HALE AND KILBURN COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF DELAWARE.

CAB-SEAT.

To all whom it may concern:

Be it known that I, RICHARD B. IVIARSH, a citizen of the Jnited States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Car-Seats, of which the following is a specification.

This invention relates to car seats and is directed to the provision of an improved form of seat-movement whereby the seatcushion is moved when the back-cushion is moved to reverse the facing direction of the seat.

The object of the invention primarily is to so improve the construction of the seatmovement as to provide a greater amount of space below the mechanism of the seat.

In the construction of car seats heretofore, effort has been made to arrange the parts of the seat-movement compactly so as to provide a substantial amount of space below the seatmovement. The amount of space provided, however, with the prior forms of seat-movements, has not been sufficient, particularly in cases where the pipes of the heating system employed in the car extend a substantial distance above the floor of the car. In recent years steel cars have been used to a considerable extent and with these cars a larger number of pipes is required in the heating system, other conditions being the-same. In order to provide ample space for such heating pipes, it is important that the parts of the seat-movement be arranged as compactly as possible so that they extend the minimum. distance downwardly below the surface of the seat-cushion. This invention is directed to the provision of a seat-movement which is an improvement over those heretofore employed in that the amount of space between the bottom of the seat-movement and the floor is greatly increased. In car seats as now made it is common to provide a seat-end at each end of the seat and connecting rails extending between these two seat-ends, the cushions and other moving parts of the seat being supported upon the connecting rails and seat-ends. In accordance with the present invention, the seat-movement is so constructed and arranged that none of the parts thereof extend below the lower edges or surfaces of the connecting-rails so that all of the space from the bottom of the rails down to the floor is available for heating Specification of Letters Patent.

pipes or other devices. The compact arrangementof the parts of the seat-movement is secured by utilizing a horizontally-disposed pivoted lever which is turned about lts pivot by the movement of the back cushion in reversing the facing direction of the seat and which is so connected to the seat-cushion or the rocker for the seatcushion as to actuate the seatcushion when the back-cushion is moved.

The preferred embodiment of the inven tion is illustrated in the accompanying drawings in which Figure 1, is a view of one end of a car-seat constructed in accordance with the present invention, Fig. 2 is a horizontal section of the mechanism shown in Fig. 1, the seat-cushion being removed, Fig. 3 is an enlarged view of certain of the parts shown in Fig. 2 and Fig. 1 is a central vertical section of the parts of the seat-movement.

Referring to these drawings, the seat-end is indicated at 5, this consisting'of a piece of sheet-metal pressed to the desired configuration. In the present instance, the seatend is formed integral with the pedestal 6 which supports one end of the seat, this pedestal being formed from two pieces of sheet-metal which are pressed into form and secured together at their edges and one of which extends upwardly to form the seatend 5. Two connecting-rails 7 are securec at their ends to the seat-end 5. For this purpose each connecting rail has its end secured to an angular end-piece 8 which end piece is riveted or otherwise secured to the seat-end 5. In the end-pieces 8 rocker-runs are formed for the reception of rocker 9 upon which the seat-cushion 10 is mounted.

The back-c11sl1ion 11 is mounted upon the seat-end in any suitable manner which will permit of moving the back-cushion from one edge to the other of the seat-cushion so as to reverse the facing direction of the seat. In the present instance the backcushion 11 is shown as supported by abacksupporting arm 12 whose lower end is sustained by and movable upon a curved track 13. This track is formed in or secured to the seat-end 5. The lower ends of the backsupporting arms 12 at opposite ends of the cushion coact with the tracks 13 in such a way that the back may be moved upon the tracks to reverse the facing direction of the seat and will be properly supported at either end of its range of movement. A lever let is pivotally mounted upon the seatend and at its upper end is connected by a pin and slot connection with the back-supporting arm 12. Preferably the lever 14 is secured to a rock-shaft 15 which extends between the two seat-ends so as to insure simultaneous movement of the mechanism at both ends of the seat.

A strip 16 of sheet-metal extends between the two rails 7 hear the ends thereof and is secured to the rails. This strip'forms a support for a recipro'catory member 17 and for a horizo'ntally-disl'oosed pivoted lever 18. The strip 16, has slot cut therein as shown at 19 which slot receives pins 20 on the member 17 so as to guide the member 17 in its recipro c'atory movement. The member 17 is reoi procated in accordance with the movemeirt' of the back-supporting arm 12 and this is effected by the lever 14: which has an extension 21 b'eyo'iid the rock shaft 15 which extension is provided with a pin 22 working in a slot 23 in the member 17; When the member 17 is recip'rocated, it turns the lever 18 about the pivotal connection 24E of that lever to the support 16; this is effected apin 25 in the member 17 working in a slot in the lever 18. The lever 18 has a pin 26 at its free end which pin enters the slot 27 formed in the rocker 9.

It will be seen that; by means of the mechanism above described, when the back is moved to reverse the facing direction of the seat, the seat-cushion will be moved in the opposite direction and will have its inclination altered in the usual manner. VVhen' the back is moved, it operates to turn the lever 14 whose pin 22 moves the member 17 lying upon the surface of the support 16. When member 17 is so moved, it turns the horizontally-disposed pivoted lever 18 about its pivot 24; lever 18 by means of its pin 26 moves the rocker 9' in the rockerruns and thus effects the desired movement of the seat-cushion. 4

The mechanism herein shown and de scribed possesses the important advantage over seat movements as heretofore made in that the parts are compactly arranged so that the maximum space is provided below the seat-movement. It will be seen by reference to Fig. 1 that the seat-movement lies wholly vabove the lowest portions of the connecting rails so that all the space from the rails down to the floor is available for other purposes. This is of special importance in steel cars in which an unusually large number of heating pipes is required and in which many forms of car-seats heretofore made could not be used because oi"; the insuiiicient space provided between the floor and the seat-movement; I have illustrated and described the constrtiction at one end billy of the car-seat but it' will be understoed that the construction is the same or substantially the same at both ends of the seat. At the wan-"end the seat be supported otherwise than upon a pedestal such as that shown but otherwise the construction is preferably identical with that illustrated.

Having described my ihve'nticn, what I claim as new therein and desire to secure by Letters Patent of the United States is A car-seat having a movable back, a seatcushion, a supporting strhcturefiif the seat cushion including a seat-end a pair of connecting rails having their ends cormected to the seat-end, a back-sdpp'orting arm mounted for movement track carried by the seat-end, a lever pivotally mounted 6h the seat-end itiid confiected to said arm for actt'l ittlllg a 'i ecip'r'ocatory lrleinber mounted for heriz'ontal movement in aplarie above the lower surfaces of said rails, having an operative connection with said lever, whereby said member is continuously moved as said lever is moved; a second lever mounted for movement abotrt a vertical axis in a plane above the lower surfaces of said rails, said lever being coiinected to said member for actuation thereby, and being connected t6 said seat-cushion to move the latter when the back is reversed, substantially as set forth. p t n This spec'ii fiojn signed and witnessed this 5th day of July, 1912.
